The aim of this study was to investigate the effects of the synthetic mesh on the ductus deferens and testicle of dogs. Ten adult male dogs were anesthetized and a 2,5X3,5 cm² polypropilene mesh was fixed in the inguinal region in direct contact with the ductus deferens, using metallic staples without dissection of the region and therefore, without manipulation. The right side, with no mesh was the control. . The operative time was 15 minutes. The animals were observed for 30 days and after that, they were again anesthetized and underwent new operation when the ductus deferens and the testicle were removed and sent to histological analysis. The histological sections of the testicle showed a focal reduction of the spermatogenesis in 20 % and a degenerative process in 20 % of the animals. In the epididimus, chronic inflammation and seminiferous tubules dilatation were observed in 70 %. A chronic inflammatory process was found in 60 % of the vas deferens. The polypropilene mesh in direct contact with the spermatic funiculus in dogs causes histological alterations with minimal reduction on spermatogenesis.
